Things we know about Matt Damon: He is a superstar with a mega-watt smile and huge hit movies under hit belt.

Forbes Magazine even called him the most dependable star in Hollywood, bringing studios an estimated $29 of profit for every dollar he gets paid.

But this year, Damon is shaking things up and taking some big chances, like with his latest film "Elysium."

"You've done action before in the Bourne films that everyone knows obviously, but what drew you to this film?" asks Anchor Kate Bolduan.

"It was the director, Neill Blomkamp, is the same guy who directed 'District 9' and I just loved that movie," says Damon.

Blomkamp grabbed attention when his low-budget $30 million alien movie went on to gross $211 million worldwide and snag 4 Oscar nominations. Damon hopes his gamble on another Blomkamp sci-fi flick will pay off as well.

I'd been waiting and hoping for years that a good science fiction movie would come along because they're really, really rare, to get a good science fiction movie that turns into a great movie," says Damon.

Set in the year 2154, Damon's latest role has him fighting his way from a ruined wastelan planet Earth, to the man-made paradise called Elysium

"What was it like? I'm always curious and – bc it becomes part of the job, to have the getting in shape for it," asks Bolduan.

"Definitely, definitely. Bc it's not something that I particularly enjoy. The diet part is not something I enjoy. But Neill had a whole kind of graphic novel that he'd put together on his computer, like a whole thing," says Damon. "And there was a picture of Max with his shirt off, staring into a mirror, with tattoos all over, in really good shape... You know, they hired this unbelievable trainer. I went to the guy with the picture and went, I need to do this. And he kind of looked at me, and went OK."

"We got a lot of work to do," says Bolduan.

"We got a lot of work to do. And that's what we did," says Damon.

For a guy with such star power, Damon also possesses an unusual quality for a Hollywood A-lister. He is still very much just a normal guy.

"Isn't that such a statement that's a shock and a compliment that someone actually calls you normal in terms of how celebrities are these days... How do you stay so normal?" asks Bolduan.

"Well my favorite answer to that that I ever heard was, someone asked George Clooney, and he said, "oh, I pay a whole team of people to do that," says Damon.
